Benefits of technology

[0009]In accordance with the present invention, multiple membranes can minimize a difference in the acoustic impedances between the transducer array and the membrane such that high-sensitivity and high-resolution 3D ultrasound images can be formed. Further, the membranes including a shielding layer made from an electrically conductive material are applied to the probe so as to shield noises or undesired signals such that high-sensitivity and high-resolution 3D ultrasound images can be formed.

Problems solved by technology

However, ultrasound signals scanned by such a probe may be distorted or include noises or undesired signals, which can hinder accurate diagnosis.

Embodiment Construction

[0014]Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

[0015]FIG. 1 schematically shows a cross-sectional view of a probe for performing ultrasound diagnosis in accordance with one embodiment of the present invention. The probe of the present invention includes multiple membranes.

[0016]Referring to FIG. 1, the probe 110 includes multiple membranes 112 and a transducer array 114 for transmitting and receiving ultrasound signals. Oil may be provided in the space between the membrane 112 and the transducer array 114 so as to facilitate the operations of the probe 110. The membrane 112 serves as a cover for protecting the transducer array 114. The transducer array 114 is formed with piezoelectric elements 114a. Further, the probe 110 includes a matching layer 115 covering the piezoelectric elements 114a, a lens 116 covering the matching layer 115 and a backing layer 117 supporting the piezoelectric elements 114a. Although...

Abstract

The present invention relates to a probe, which is adapted to match acoustic impedances and shield undesired signals, and an ultrasound diagnostic system configured to use such a probe. The probe for conducting ultrasound diagnosis includes a transducer array for transmitting ultrasound signals to a target object and receiving the ultrasound signals reflected from the target object. The probe of the present invention also includes multiple membranes for covering the transducer array, wherein the multiple membranes include at least two membranes formed from different materials and having different thicknesses.

Description

TECHNICAL FIELD[0001]The present invention generally relates to a probe for conducting ultrasound diagnosis and an ultrasound diagnostic system using the same, and more particularly to a probe adapted to match acoustic impedances and shield undesired signals and an ultrasound diagnostic system using the same.BACKGROUND ART[0002]An ultrasound diagnostic system has become an important and popular diagnostic tool due to its wide range of applications. Specifically, due to its non-invasive and non-destructive nature, the ultrasound diagnostic system has been extensively used in the medical profession. Modern high-performance ultrasound diagnostic systems and techniques are commonly used to produce two or three-dimensional (2D or 3D) diagnostic images of a target object.[0003]The ultrasound diagnostic system generally uses a probe, which includes a transducer array having a plurality of transducers, to transmit and receive ultrasound signals. The ultrasound diagnostic system forms ultras...
